摘要

A method for driving a light-emitting diode includes the step of modulating the luminance of the light-emitting diode with current density within the range of 20 A/cm2 or less. The light-emitting diode includes a p-type layer, an n-type layer, and a light-emitting layer disposed therebetween and having an indium-containing quantum well structure. Each of the p-type layer, the n-type layer, and the light-emitting layer includes a nitride-based group III-V compound semiconductor crystal having a wurtzite structure. The light-emitting layer has a main surface inclined at an angle of 0.25° to 2° with respect to a c-plane.
